POTSDAM — Two people were airlifted to University of Vermont Medical Center after a state trooper, responding to an alleged domestic dispute, crashed into a 2016 Chevrolet Equinox that was pulling out of Walmart on U.S. Route 11 Saturday.

Preliminary investigation determined that Trooper Matthew Baker was traveling east on U.S. Route 11 around 10:30 a.m. with emergency lights and siren activated responding to a call for a physical domestic dispute, according to state police.

As Trooper Baker approached the intersection near the Walmart, the light at the intersection turned red, officers said. He then struck a Equinox, which was being driven by Megan L. McAnulty, 25, Norwood.

Police said Trooper Baker, who suffered minor injuries, immediately provided medical assistance to the occupants of the Equinox.

The road was shut down for several hours.  

McAnulty was reportedly airlifted to the University of Vermont Medical Center with life-threatening injuries.

The front passenger, Wyatt Parker, 28, of Mannsville, was transported to Canton-Potsdam Hospital and later transferred to the University of Vermont Medical Center with life-threatening injuries, officers said.

Two passengers in the rear of the vehicle were transported to Canton-Potsdam Hospital with minor injuries.
